Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules based on phenylpropanoic acid derivatives. Its structure allows for selective substitution reactions, making it valuable in constructing complex aromatic compounds. Commonly employed in organic synthesis to introduce fluorinated and brominated aromatic moieties, which can enhance metabolic stability and binding affinity in drug candidates. Also utilized in the preparation of agrochemicals and specialty chemicals requiring specific halogen substitution patterns.
